SSA study of early polyethylenes degradation stages. Effects of attack rate, of average branch length, and of backbone polymethylene sequences length distributions
(Elsevier, 2012-10-24)
Low-density polyethylenes have been attacked by free radicals in the presence of oxygen to promote chains scission, aiming at showing effects of the molecular structure on the thermal behavior as determined by using a ...
Corona charging and potential decay on oxidized polyethylene surfaces
(Elsevier Sci LtdOxfordInglaterra, 2014)
Estudo da correlação estrutura-propriedade de blendas de polietileno linear de baixa densidade (PELBD) com polietileno de ultra alto peso molecular (PEUAPM) modificadas por peroxidoStudy of the structure-property correlation of low density linear polyethylene blends (LLDPE) with peroxide modified ultra high molecular weight polyethylene (UHMWPE)

Laser-induced breakdown spectroscopy applied to the rapid identification of different types of polyethylene used for toy manufacturing
(2020-01-01)
The identification of plastics is of great importance to recycling companies, as the littering of plastic wastes has rapidly increased because of the extensive use of plastics. To maintain the economics of recycling extremely ...
Mechanical and antimicrobial properties of low-density-polyethylene/MgO nanocomposites
(2022)
Low-density polyethylene (LDPE) nanocomposites containing magnesium oxide (MgO) nanoparticles are obtained by melt mixing. MgO nanoparticles ca. 29 ± 2 nm are synthesized by sol–gel and organically modified on the surface ...
Determination of impact fracture toughness of polyethylene using arc-shaped specimens
(Pergamon-Elsevier Science Ltd, 2002-07)
This paper describes a methodology for the determination of the impact radial fracture toughness GIC, of cylindrical polymeric molded parts using arc-shaped specimens. The proposed methodology is an extension of the ISO/DIS ...

Tensile Mechanical Behavior of Linear High-Density Polyethylenes Modified With Organic Peroxide
(John Wiley & Sons Inc, 2003-09)
The molecular structure of several high-density polyethylenes of different molecular weights and vinyl contents was modified without altering their thermoplastic character using an organic peroxide. Chain linking was the ...
Maxillary Bone Defect Reconstruction Using Porous Polyethylene Implants
